Cornual nerve block Dehorning in cattle

############################# Video Source: www.youtube.com/watch?v=NyIzKzOdT30

The horn and horn base in cattle are innervated by the cornual branch of the zygomaticotemporal nerve, also known as the lachrymal nerve (J3.80.w1, J234.12.w2). It is a branch of the ophthalmic division of the trigeminal nerve (B205.12.w12). The zygomaticotemporal nerve, which is relatively superficial, 7 to 10 mm deep and covered only by a thin layer of frontalis muscle and the skin, can generally be palpated halfway from the lateral canthus of the eye super to a point 3cm from the lateral base of the horn, between the frontalis and temporal muscles. In large bulls the nerve lies deeper, at about 2.5 cm. • Keywords • #Cornual nerve block • #Dehorning • #cattle • #injection • Copyright Disclaimer under Section 107 of the copyright act 1976, allowance is made for fair use for purposes such as criticism, comment, news reporting, scholarship, and research.
